Exploring the underground connections between trees      (via sciencedaily.com)     Original source 

Fungal networks interconnecting trees in a forest is a key factor that determines the nature of forests and their response to climate change. These networks have also been viewed as a means for trees to help their offspring and other tree-friends, according to the increasingly popular 'mother-tree hypothesis'. An international group of researchers re-examined the evidence for and against this hypothesis in a new study.

Symmetric graphene quantum dots for future qubits      (via sciencedaily.com)     Original source 

Quantum dots in semiconductors such as silicon or gallium arsenide have long been considered hot candidates for hosting quantum bits in future quantum processors. Scientists have now shown that bilayer graphene has even more to offer here than other materials. The double quantum dots they have created are characterized by a nearly perfect electron-hole-symmetry that allows a robust read-out mechanism -- one of the necessary criteria for quantum computing.

Previously unknown intercellular electricity may power biology      (via sciencedaily.com)     Original source 

Researchers have discovered that the electrical fields and activity that exist through a cell's membrane also exist within and around another type of cellular structure called biological condensates. Like oil droplets floating in water, these structures exist because of differences in density. Their foundational discovery could change the way researchers think about biological chemistry. It could also provide a clue as to how the first life on Earth harnessed the energy needed to arise.
